Until now, the production for Transformers 4 has took place in Downtown Detroit, but new reports claim filming will be moved to Lansing, Michigan over the weekend.

According to On Location Vacations, Transformers 4 will be filmed at General Motors Delta Township Assembly Plant on Saturday, Aug. 10 and Sunday, Aug. 11.

A movie publicist told OLV it will be a closed set and no visitors will be allowed, and there's no word whether the film's stars, Mark Wahlberg and Stanley Tucci, will be on set. A GM spokesperson also said the plant in Lansing will not be the only one featured in the movie.

After this weekend, the action flick will return to Detroit, its location since late July. On Thursday, a Detroit resident posted a video (below) of Mark Wahlberg on set in a blue truck. After the actor waves to fans and the camera begins rolling, he enters a messy scene full of dust, just after a crowd of people fled the area.

Another video (below) posted on Wednesday shows what the crowd might have been running away from--a train fell from the sky. The video, "Transformers 4 filming People Movers derailment," shows a train being dropped onto the Tokyo set with extras fleeing the incident.

Mark Wahlberg, who usually wears tight shirts, was spotted on set earlier this month, showcasing a bloody face with scratches. He was also seen carrying a massive twin-bladed weapon to protect co-stars Nicola Petlz and Sophia Myles. (Click here to see the photos)

"We're taking the story that you've seen - the story we've told in three movies already - and we're taking it in a new direction," Bay told the LA Times. "But we're leaving those three as the history. It all still counts."
